Employees (76 women, 15 men; mean age = 44.61 years old; SD = 10.84) of a nonprofit eldercare program completed measures of public service motives, community self-efficacy, sense of community with coworkers, and caregiver satisfaction and stress. Participants also identified whether they had a mentor in their life, someone with more experience who provided support and guidance to them. Employees with mentors (n = 47) compared to those without a mentor (n = 44) indicated (controlling for social desirability) (1) significantly stronger motives to help others as boosting self-esteem, understanding of social problems, and reflection of one's values; (2) significantly stronger beliefs in a common mission and a desire to be supportive of peers; and (3) less caregiver stress in helping older adults.
